ADD GASOLINE (See Fig. 8)
• Fill fuel tank to bottom of tank fi ller neck. Do not over-
fi ll. Use fresh, clean, regular unleaded gasoline with
a minimum of 87 octane. Do not mix oil with gasoline.
Purchase fuel in quan ti ties that can be used within 30
days to assure fuel freshness.
CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open fl ame.
Alcohol blended fuels (called gasohol
or using ethanol or methanol) can at-
tract moisture which leads to separation
and for ma tion of acids during storage.
Acidic gas can damage the fuel sys-
tem of an engine while in storage. To
avoid engine problems, the fuel system
should be emptied before stor age of 30
days or longer. Drain the gas tank, start
the engine and let it run until the fuel
lines and carburetor are empty. Use
fresh fuel next season. See Storage
In struc tions for additional information.
Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
